-Specification of Letters Patent.

Patented May 2, 1916.

Application filed January 27, 1916. Serial No. 74,581.

To all whom it may concern: I

Be it known that I, ELLSWORTH B. A. ZWOYER, a citizen of the United States, and resident of Perth Amboy, county of Middle sex, State of New Jersey, have invented a certain new and useful Press, of which the following is a specification.

This invention relates to improvements in presses for making briquets or similar articles or for crushing or embossing, and has for its objects: First: To bring certain parts of the two rolls into operative position with facility, even when the press is in operationand under load. Second: To permit readjustment for wear of the rolls and at the same time keep certain parts of the two rolls in operative position. Third: To facilitate adjustment of the rolls in mutual relation and resist strains on the bearings. Fourth: To render the press interchangeable so that it may be used as a right or left hand press.

These and further objects will more fully appear from the following specification and accompanying drawings, considered together or separately.

In the drawings; Figure 1 is a plan view of a press for making brique-ts embodying my invention; Fig. 2 is a side view thereof; Fig. 3 is a sectional view on the line 3-3 of Fig. 1; Fig. 4 is a sectional view on the line 4 of Fig. 1; Fig. 5 is a diagrammatic plan view of a press when used as a right handed press; Fig. 6 is a similar view of the same press when used as a left handed press; Figs. 7, 8, 9 and 10 are diagrammatic views of certain parts of a press for making briquets showing adjustment of the rolls for wear and wherein the pockets are kept in coincidence after such adjustment.

In all views like parts are designated by the same reference characters.

The press illustrated in Figs. 1 to 10 of the drawings comprises a base 1 having a bed 2 thereon. On this bed are suitable ways 3, 3. Mounted upon these ways is a sub frame 4. This subframe is shown in Fig. 1 preferably as continuous. It may be made of one or more pieces. The ends of the frame inclose the rolls. Mounted upon the subframe are moving bearing boxes 5, 5 and fixed bearing boxes 24, 24, see Fig. 4. A roll shaft 6 is carried in the bearings 5. A second roll shaft 7 is carried in the bearings 24. Rolls 8 are mounted upon the shaft 6 and rolls 9 are mounted upon the shaft 7 mounted upon the shaft 7.

Carried by the subframe and located above the rolls is a hopper 10. A gear ll-is mounted upon the shaft 6 and a similar gear 12 is A drive shaft 13 18 mounted in suitable bearings on the base and a jack shaft 14 is mounted in suitable bearings also upon the base and parallel to the drive shaft. A pinion 15 is carried upon the drive shaft 13 and meshes with the gear 11, and a second pinion 16 is mounted upon the jack shaft 14 and meshes with the gear 12. A suitable drive pulley 17 is mounted upon the drive shaft 13. Suitable matching gears 21 are carried upon the two shafts 13 and 14 and intergage. The movlng bearing boxes 5, 5 are suitably adjusted by means of screws 18, see Fig. 5. These screws are provided with a suitable worm gear 19 actuated by a shaft which is turned by means of a crank 20. Suitable screws 22 carried by the bed 2 are adapted to move the subframe in one direction and similar screws 23 also carried by the bed engaging with the subfrarne are adapted to move the latter in the opposite direction. The rolls are pro vided with suitable pockets 25, of such a shape as to make a briquet of a desired size and configuration. 7

With the parts assembled as shown, power being applied to the pulley 17 it will rotate the drive shaft 13. The jack shaft 14 will, through the agency of the matching gears 21, also be rotated in the opposite direction at the same speed. The pinions 15 and 16 will rotate the gears 11 and 12 respectively, also at the same speed, and these gears will rotate theroll shafts 6 and 7 and with them the rolls 8 and 9. In the course of time the faces of the rolls will wear so that there is a separating interval between them, as shown in Fig. 8. When this occurs imperfect briquets will be produced. It is desirable that the rolls be adjusted to take up this wear so that they will be placed in a position, shown in' Fig. 4, in which the faces of the rolls will be close together. The adjustment for wear is-made by the moving of the box 5 in a direction toward the box 24. This is obtainedby rotating the crank 20 which will turn through its shaft, the worm gear 19, the two screws 13, 18 engaging with the two boxes 5, 5. This will simultaneously move the two boxes in the direction toward the shaft 7. This movement will continue until the two shafts are in proper relative position to make up for the loss through wear on the rolls. As the boxes 5, 5 are moved and with them the shaft 6, the gear 11, mounted on the shaft 6, will rotate upon the pinion 15, the latter being stationary owing to the engagement of the matching gears 21 with each other.

Therefore, as the shaft 6 is moved toward unscrewing the screws 22 and screwing up the screws 23 to the desired amount, mov ing the subframe in the direction of the horizontal arrow a in Fig. 10. While this is being done the gears 11" and 12 will rotate upon the fixed pinions 15, 16, both in the same direction, as shown by the curved ar rows 1;, b in Fig. 10. The result will be that both rolls turning in the same direction, their passing faces will turn in opposite direction. This movement of the subframe will be continued until the pockets are in exact coincidence. When this is attained the screws 22 can be screwed into contact with the frame and the lock nuts upon these screws can be tightened to prevent any further movement.

The adjustment of the boxes in relation to one another may be easily attained by 7 simply rotating the crank 20. Any slight adjustment for wear may therefore be taken up without stopping the press. The subframe encircling the two rolls as shown produces a very strong construction and will resist strains, localizing all stresses due to the material passing between the rolls.

The press has the further advantage that it may be used either as a right handed or left handed press. The manner in which this is done is diagrammatically illustrated in Figs. 5 and 6. If it is desired to change the right handed press (Fig. 5) into a lefthanded press (Fig. 6), without changing the position of the base 1 and without changing the end upon which the drive pulley is, it'is merely necessary to reverse the position of the subframe 4 which will reverse the position of the rolls 8 and 9. The drive shaft and jack shaft -are interchanged.- When thus interchanged the parts will be in the position shown in Fig. 6. The roll 8 will be driven through the agency of the drive shaft 13 and the roll 9 will be driven through the agency of the jack shaft 14 as before, but the parts will be reversed as shown.

A press made according to my invention may be so adjusted that the rolls will perfectly match while the press is at rest or running, without material passing through. When material is in the press and between the rolls, one of them may have a tendency to move upward in its bearings, thus placing the pockets out of alinement. This may particularly occur after the bearings wear. When this happens the pockets can be very readily restored to alinement by loosening one set of horizontal screws 22 or 23 and tightening the other set, as hereinbefore described. This mav be done while the press is in operation even when running under load. It will, therefore, be seen that a very desirable feature of the invention is that the rolls may be adjusted to bring the pockets into coincidence irrespective of the wear on the latter. This feature is useful when the press is first built. It is a very difficult matter to properly key a roll to a shaft in relation to the matching gear so that the pockets are in exact alinement.

According to this invention no care at all is to be taken in keying the roll to the shaft for the purpose of securing alinement of the pockets. The alinement may be obtained afterward in the manner hereinbefore described.

While I have described my invention particularly as applied to a press for making briquets, it is to be understood that the invention may not be so limited as the rolls may be used for other purposes.

In accordance with the provisions of the patent statutes, I have described the principle of my invention, together -With the apparatus which I now consider to represent the best embodiment thereof; but I desire to have it understood that the apparatus shown is merely illustrative and that the invention may be carried out in other ways.
